CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 298,577, dated May 13, 1884.

Application filed October 18, 19588.

To all whom it may concern.:

Be it known that I, Elvin. HUGO ADoLrrr HAUPT, a citizen ofthe German Empire, residing at Dolgeville, in the county of Herkimer and State of. N ew York, have invented new and useful Improvements in Car-Couplings, of which the following is a specification.

This invention relates, especially, to automatic couplings; and it consists in the novel construction and arrangement of parts hereinafter described, whereby such couplings are automatically locked not only in a closed position, but also in an opened position, to be released, when desirable, by simply depressing a certain part ofthe device.

In the accompanying drawings, Figure l showsacoupling,partly in top View and partly in horizontal section, embodying my invention. Fig. 2 is an inverted plan view thereof. Fig. 3 isa horizontal section showing the parts in a different position from that shown in Fig. 1. Fig. 4: is a plan View showing the parts in a corresponding position to Fig. 1. Fig. 5 is a longitudinal section on the line x x, Fig. 4. Fig. 6 is a crossssection on the line y y, Fig. 2. Fig. 7 is a like section on the line .e e, Fig. 4.

Similar letters indicate corresponding parts.

The letter A designates a draw-head constructed with a pocket, B, at or near one end, to open in an upward direction, this pocket being closed under normal conditions by a cap-plate, O, which is fastened to the properpart of the head.

In the pocket B is arranged a rack-bar, D, between stops D' D2, which also act as guides for the bar, and which are at such distances apart from each other as to allow the bar a slight longitudinal motion.

To one end of the rack-bar D is connected a return-spring, a, which acts thereon with a tendency to draw it in the direction of the stop D', so that under normal conditions the bar abuts against this stop under the impulse of the spring.

Into the teeth of the rackbar D meshes a rotating pinion, E, which is arranged in alateral projection, G', of the bolt or coupling-pin G on an axial spindle, b, which extends upward through a slot, d, in the cap-plate C, and is squared at the upper end to receive a key for (No model.)

turning it. The bolt G is fitted into a guidegroove, e, of the pocket B, to slide therein, and is subjected to the action of a spring, f, having a tendency to force the same, in the direction of the arrow shown in Fig. 3, from the position shown in that figure, which is its rear or opened position, to that shown in Fig. l, which is its closed position.

In the bottom of the pocket B are arranged two bits or catches, H H', which are beveled in opposite directions and serve to lock the bolt G in its opened and closed positions, respectively, as hereinafter explained. Each of the catches H H' is pivoted, by means of its shank, to move in a substantially vertical plane, and is subjected to the action ofaspring, g or g', (best seen in Fig. 2,) having a tendency to force it to an upper or 'normal positionnamely, through and above the level of the bottom of the pocket B into the path of the projection G' of the bolt. y

Levers I I' serve to retract the catches H Hf against the action of the springs g g' in the following manner: The lever I oscillates in a horizontal plane on a pivot-screw, i, and engages a notch, s, of the catch H at one end, while it is connected to thev rack-bar D at the other end through a slot, o, in the bottoni of the pocket B in such a manner that when the rack-baris displaced against its return-spring a it acts on'the lever I to throw the proper end thereof out of said notch of the catch onto a plain portion of the latter, asindicated in Fig. 5, whereby the catch is forced in or downward. The lever I oscillates in a vertical plane on a pvot-shaft, k, and engages a notch of the catch H' at one end, it being iixed to the shaft, together with a second lever, J, to which is connected a vertical push-bar, J', in such a manner that when this bar is depressed the lever I' shares its motion and displaces the catch. rIhe push-rod I extends upward through the cap-plate C, and is provided at't-he upper end with a head or button, Z, whereby it may be conveniently depressed by the foot. Protection is afforded to the catches H H'and concomitant parts by arranging the same in a recess, M, formed at the proper place in the draw-head A, such recess being provided with a suitable cover.

Adjacent to the pocket B, in an inward di- IOO rection, the draw-head A is provided with a mouth, N, to receive the coupling-link O of another draw -l1ead. In this mouth is arranged a projection, 1?',of a tumbler, ]?,which works in a pocket, Q, of the draw-head, and is subjected to the action of a spring, Q', having atendency to force the same in an outward direction. rIhe tumbler P has a second projection, I, which is arranged in a branch, Q2, of the pocket Q, to intersect a channel or passage Gwhich receives the bolt, such channel being continued from one to the other side of the mouth or link-receptacle N of the drawhead. Vhen the bolt G is in a closed position, as shown in Fig.` l, the catch H engages the ,projection G thereof, and thus locks the bolt in the position named. Then it is desired to retract the bolt, the pinion E is turned in the direction of the arrow shown in Fig. l by means of a key iitted to the spindle b, as before stated, and in the initial movement of the pinion the rack-barD is thereby displaced against the action of its spring a to the extent allowed by the stop D, as indicated in Fig. 4, while during the movement of the bar it acts on the lever I to cause the retraction of the catch H, as before explained, so that the bolt is permitted to pass over the catch. As the motion of the pinion E is continued, the bolt travels inward, and its projection G' comes in contact with and rides over the catch H', the bevel of this catch being proper for this purpose, while when the projection has cleared the catch the latter engages therewith, as shown in Fig. 3, thus locking the boltin what constitutes its opened position. `To release the bolt the push -bar J is depressed to cause the retraction of the catch H', whereby the bolt is set free and allowed to follow the action of its spring f, under the impulse bolt, so that the latter may enter the link, the

catch H at the same time re-engaging the bolt, so that it becomes locked. In the motions of the bolt G the spindle b travels in the slot d of the cap-plate, and when the bolt has reached either extreme position this slot maybe closed by a suitable cover.

In applyingy the coupling to use the adjacent ends of two cars are each provided with a draw-head A similar to the other, the link O of one head being arranged opposite to the mouth N of the other head, as shown in Fig. 1. Said link O is pivoted at the inner end to a slide, It, which is arranged in a pocket, It', of the draw-head, and is exposed to the action of a spring, R2, having a tendency to force it inward, so that the spring tends to counteract the draft on the link, while the latter is left free to perform the required lateral movements. V

In the center of the draw-head is arranged a buffer, S, of any usual or suitable construction.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination of the draw-head having the pocket B, the rack-bar D, arranged between stops in said pocket, the returnspring of the rack-bar, the spring-impelled bolt having the lateral projection G', the pinion E, arranged in said projection of the'bolt to engage the rack-bar, the axial spindle of the pinion, the bolt-catches C C', and means, substantially such as hereinbefore described, for retracting said catches.

2. The combination of the draw-head having the pocket B, the rack-bar D, arranged between stops in said pocket, the return-spring of the rack-bar, the spring-impelled bolt having the lateral projection G', the pinion E, arranged in said projection of the bolt to engage the rack-bar, the axial spindle of the pinion, the catches C C', the retracting-lever I, engaging the catch C and connecting with the rack-bar, the retracting-lever I', engaging the catch C', and the push-bar J', acting on the lever last mentioned.

3. The combination of the draw-head having the 4pockets B Q, the mouth or link-receptacle N, and the bolt-passage G2, the rack-bar D, arranged between stops in the pocket B, the return-spring of the rack-bar, the springimpelled bolt having the lateral projection G', the pinion E, arranged in said projection of the boltto engage the rack-bar, the axial spindie of the pinion, the catches OC', means, substantially as herein described, for reti-acting the catches, and the tumbler P,working in the pocket Q, and having projections P' Ii-one arranged in the link-receptacle, and the other arranged to intersect the bolt-passage.

4. The combination, with the draw-head having the-mouth or link-receptacle N, and coupling mechanism, substantially such as herein described, of the slide R, the spring acting on the slide, and the link pivoted to the slide at the inner end.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
